Canon EOS 5D Mark III SLR Digital Camera Sample Photos

"Better looking" yes.. ;=)
The phrase I would commonly use would be "better feel" but too many digital 'photographers' today don't know what that means..
I do not think the majority of the images are equal, in comparison, but I will agree with you in regard to the 5DmkIII being the desirable/preferred average of two extremes - Aurea Mediocritas.

I am loving the images from the 5DmkIII..!
Most of what I have seen have a visually satisfying 'real' look in the images, as opposed to the 'gritty' look of its major competitor, in addition the backgrounds have a smoother appearance.

Even though you do not read much about it, Canon really has improved the red channel performance and it is showing. There is still some detail smudging in red cloth and such, but much better than in the past.

Understand this is not some fanboy rave, I own both Canon and Nikon equipment, but if my next comment prods D800 users to post better pictures of what they believe is the best camera in the world - so be it.

***The majority of the 5DmkIII images posted so far are much better looking and have greater appeal than the majority of the D800 images posted!***
